There are 1 questions in this calculation: for each question, the 1 derivative of y is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ y*2e^{yx} - ye^{yx} - y*2xe^{yx}\ with\ respect\ to\ y：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = ye^{xy} - 2xye^{xy}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( ye^{xy} - 2xye^{xy}\right)}{dy}\\=&e^{xy} + ye^{xy}x - 2xe^{xy} - 2xye^{xy}x\\=&e^{xy} + xye^{xy} - 2xe^{xy} - 2x^{2}ye^{xy}\\ \end{split}\end{equation} \]
